1.3 Coordination

The purpose of an initial Consultation Coordination Officer's (CCO) meeting is to
discuss the scope of the FIS. A final CCO meeting is held to review the results of
the study.

A meeting was held on July 8, 1976, to discuss streams studied in the original
study for Douglas County and the methods of study to be used. The meeting was
attended by representatives of FEMA; the Douglas County Planning and Zoning
Department; the UDFCD; and Howard, Needles, Tammen and Bergendoff, the
study contractor. Subsequent meetings and calls to the Douglas County Planning
Director provided pertinent zoning and current development information.

For the September 30, 1987, restudy for Douglas County, an initial community
coordination meeting was held on April 10, 1984, to set priorities for study
reaches. The meeting was attended by representatives of FEMA; CWCB;
UDFCD; U.S. Soil Conservation Service (SCS); the Douglas County Planning
Department; and J.F. Sato and Associates, Inc., the study contractor. The study
area was subsequently modified at the direction of FEMA to include additional
reaches to be studied by approximate methods. The final study scope was
reviewed with Douglas County Planning Department, Town of Castle Rock, and
Engineering Department staff at a meeting on September 17, 1984.

An intermediate community coordination meeting for the Douglas County restudy
was held on July 29, 1985, to discuss the findings of the study. Representatives of
